NAME

SYNOPSIS

DESCRIPTION

The crl2pkcs7 command takes an optional CRL and one or more certificates and converts them into a PKCS#7 degenerate "certificates only" structure.

COMMAND OPTIONS

-inform DER|PEM

This specifies the CRL input format. DER format is DER encoded CRL structure.PEM (the default) is a base64 encoded version of the DER form with header and footer lines.

-outform DER|PEM

This specifies the PKCS#7 structure output format. DER format is DER encoded PKCS#7 structure.PEM (the default) is a base64 encoded version of the DER form with header and footer lines.

-in filename

This specifies the input filename to read a CRL from or standard input if this option is not specified.

-out filename

specifies the output filename to write the PKCS#7 structure to or standard output by default.

-certfile filename

specifies a filename containing one or more certificates in PEM format. All certificates in the file will be added to the PKCS#7 structure. This option can be used more than once to read certificates form multiple files.

-nocrl

normally a CRL is included in the output file. With this option no CRL is included in the output file and a CRL is not read from the input file.

EXAMPLES

Create a PKCS#7 structure from a certificate and CRL:

openssl crl2pkcs7 -in crl.pem -certfile cert.pem -out p7.pem

Creates a PKCS#7 structure in DER format with no CRL from several different certificates:
